gsl-random is definitely worth a try for performance. I recently did a
rough benchmark (not rigorous) of Control.Monad.Random, which uses
System.Random, and Control.Monad.MC, which uses GSL.Random.
Control.Monad.Random took about 3.6 times longer to generate a few
million random numbers compared to Control.Monad.MC, and used five times
as much heap. The GSL-based version generated about 340,000 random
numbers per second on a 1.8GHz notebook.
